* tests/sighook: Fix Valgrind compatibilityTavian Barnes10 days1-39/+43
| | | | | | | | | | | | | | | | | | | | Valgrind does not deliver async signals in a timely manner; by default, it polls for new signals every 1,000 basic blocks. That means we can get SIGALRM delivered after timer_delete(), or kill(SIGSEGV) never delivered after pause(). Fix the timer_delete() issue by reordering the cleanup path. Valgrind always polls pending signals after pthread_sigmask(), so call that between timer_delete() and sigunhook(). Fix the pause() issue by sleeping in a loop instead. Note that --fair-sched=yes is required to avoid starvation of the background thread.

|
* build: Check for compound literal storage-class supportTavian Barnes2025-01-073-1/+8
| | | | This lets us use them on GCC >= 13, even before C23.

* sighook: Always re-raise faults on macOSTavian Barnes2024-12-222-0/+11
| | | | | | | | | | macOS always fills in si_code for SIG{BUS,ILL,SEGV} as if it were a real hardware fault, so returning from the handler is not guaranteed to re- trigger the signal. Fixes: aecdabb ("sighook: Return instead of re-raising for faults") Link: https://chromium-review.googlesource.com/c/crashpad/crashpad/+/2386463/4/util/posix/signals_test.cc Link: https://github.com/chromium/crashpad/commit/e0d8a0aa01ac176804077f1f128ccc894c098f79

* sanity: New sanitize_resize() functionTavian Barnes2024-12-162-16/+33
| | | | | This wraps __sanitizer_annotate_contiguous_container() to give byte-precise tracking of usable allocation sizes with ASan.
* sanity: Get rid of sanitize_ignore()Tavian Barnes2024-12-162-11/+6
| | | | | It's probably nicer to avoid evaluating expensive arguments when not sanitizing, rather than relying on the optimizer to clean them up.

|
* ioq: Submit and pop requests in batchesTavian Barnes2024-12-035-17/+44
| | | | | The new ioq_submit() function is now necessary to call to ensure the pending request batch is flushed.
* ioq: Add more io_uring setup flagsTavian Barnes2024-12-031-20/+55
|
* ioq: Refactor io_uring submission logicTavian Barnes2024-12-031-94/+145
|
* ioq: Use ioq_batch for both pushing and poppingTavian Barnes2024-12-031-47/+84
|
* ioq: Add a hash function between slots and monitorsTavian Barnes2024-12-031-1/+11
| | | | | | This helps avoid situations where multiple waiters block on different slots using the same monitor, which happened more often than expected due to correlations caused by batching.
* ioq: Prefetch pointers before popping themTavian Barnes2024-12-032-8/+10
| | | | | Also, cache-align struct ioq_ent to avoid false sharing when two workers are handling neighbouring requests.
* bench/ioq: New ioq microbenchmarkTavian Barnes2024-12-032-1/+332
|
* ioq: Add an ioq_nop() operation for benchmarkingTavian Barnes2024-12-023-0/+62

|
* sighook: Return instead of re-raising for faultsTavian Barnes2024-11-231-5/+11
| | | | | | | | | | | This makes the death look exactly like it would if we didn't handle the signal at all. Coredumps will point at the right instruction, segfaults will get logged in dmesg again, etc. Technically POSIX says this is undefined, but if we get a fault, we've already done something undefined anyway ;) Link: https://github.com/rust-lang/rust/issues/26458
* sighook: Check for SA_RESTART before using itTavian Barnes2024-11-231-1/+7
| | | | QNX doesn't support SA_RESTART.
